Roll python deps & add pigweed's (#4168)

This will help avoid issues like the one fixed by #4165, where a pip
package used by pigweed updated underneath us and broke.

These are gathered from install_requires in setup.py of packages we
install. Currently we don't have a way to fail the build if there's an
unpinned dep; they'll have to be found manually and added to
requirements.in.
